Assuming the earth is a sphere with a radius of 3,960 miles, determine the distances between the cities. Place the city on the map below and determine in which country each city is located. City Latitude Distance from previous city Country Saint Petersburg 59° 57’ N Eskisehir 39° 47’ N Pietermaritzburg 29° 37’ S http://alabamamaps.ua.edu/contemporarymaps/world/world/ Trigonometry – Monumental Distances Find the longitude and latitude of the White House and the U.S. Capitol. A monument to George Washington was planned to be located directly south of the White House and directly west of the Capitol. Determine the longitude and latitude of the monument. This position is now indicated by a marker called the Jefferson Stone or Jefferson Pier. If the radius of the earth is r1 = 3,960 miles, determine the distance between the White House and the monument (Jefferson Stone) in both miles and feet. Determine the radius, r2, of the latitudinal circle that runs through the Capitol and use it to find the distance between the Capitol and the monument (Jefferson Stone) in both miles and feet. This planned location for the Washington Monument was found to be unsuitable to support the monument and it was moved 371.6 feet east and 123.2 feet south. Determine the distances and angles between the current Washington Monument, the White House, and the Capitol. The original design for the Washington Monument. (Library of Congress) Building the Washington Monument The original 1791 plan for Washington, D.C., included an equestrian statute of George Washington. When construction of the Monument finally started in 1848 with the laying of the cornerstone, the proposed monument was very different from the one originally planned. The new design, however, did include a statute of Washington dressed as a Roman driving a six horse chariot. In 1854 the Washington National Monument Society ran out of money and construction on the obelisk stopped at a height of 152 feet. By the time construction resumed in 1880, research had been done on the shape of Egyptian obelisks and the design of the Washington Monument was changed again to reflect this new information. (Library of Congress) Starting with the 1854 section of the monument and using the following characteristics found in traditional obelisks, complete the drawing of the Washington Monument. 1. The overall height of the obelisk was 10 times its baseline. 2. The obelisk walls would converge at a height 20 times the baseline. 3. The angle of the pyramidion seldom varied from 73°. 4. The height of the pyramidon was equal to the baseline. 5. The obelisk walls tapered at about a quarter inch per foot. 1. The overall height of the obelisk was 10 times its baseline. 2. The obelisk walls would converge at a height 20 times the baseline. 3. The angle of the pyramidion seldom varied from 73°. 4. The height of the pyramidon was equal to the baseline. 5. The obelisk walls tapered at about a quarter inch per foot. Linear Equations and the Washington Monument An equestrian statue of George Washington was first proposed by Congress in 1783. In the original plan for Washington, D.C., the statute was to be placed directly south of the White House and directly west of the Capitol. The position was shifted a little and construction of the Washington Monument started in the 1840’s and was completed (after some major redesign) in the 1880’s. The original plan for the Washington Monument. (Library of Congress) Using the drawing, insert a set of axes and determine the equations of lines that would form the Washington Monument. Building the Washington Monument It took many years to build the Washington Monument. In fact the monument you see in pictures or when you visit Washington, D.C. is not the way it was originally designed. The original plan for the Washington Monument. The Washington Monument was going to be built through donations from the American people and about $300,000 was collected. When a person donated to the monument, they received a certificate of thanks. The amount collected did not cover the cost of the monument and when money ran out in 1854, the construction on the monument stopped for almost thirty years. This is one proposal, submitted by Vinnie Ream Hoxie, on how to finish the monument when construction stopped in 1854. After the Civil War, Congress appropriated $1,000,000 to complete the Washington Monument the way it currently stands. Additions to the Monument, such as fountains and gardens were proposed in 1902 but were not completed. The ring of flags that currently surround the Monument were added in 1959. The drawing provides a timeline of the construction of the monument. Determine what percentage of the Monument’s finished height was completed during each of the indicated time frames. The drawing provides a timeline of the construction of the monument. For each time frame (except the top), the completed section would be a truncated pyramid or frustum. If a and b represent the base and top side lengths and h is the height, the volume of the truncated pyramid can be calculated using . Determine what percentage of the Monument’s finished volume was completed during each of the indicated time frames. Trigonometry – The Vietnam Veterans Memorial The Vietnam Veterans Memorial was designed by Maya Ying Lin and consisted of two long triangular black walls. The vertex of the walls formed an obtuse angle, with one wall pointing to the north-east corner of the Lincoln Memorial and the other wall pointing to north-west corner of the Washington Monument. The names of more than 58,000 Americans who died or remain missing from the Vietnam Was are inscribed on the walls. If the two walls form an angle of 125° and are each 246¢ 8 5/8² long, what is the distance between the ends of the walls. Trigonometry – The Vietnam Veterans Memorial and the Mall The Vietnam Veterans Memorial was designed by Maya Ying Lin and consisted of two long triangular black walls. The vertex of the walls formed an obtuse angle, with one wall pointing to the north-east corner of the Lincoln Memorial and the other wall pointing to north-west corner of the Washington Monument. The names of more than 58,000 Americans who died or remain missing from the Vietnam Was are inscribed on the walls. The two walls form an angle of 125° and are each 246¢ 8 5/8² long. The west wall points to the north-east corner of the Lincoln Memorial 900 ft. away from the end of the wall. The east wall points to the north-west corner of the Washington Monument 3500 ft. away from the end of the wall. Find the distance between the northeast corner of the Lincoln Memorial and the northwest corner of the Washington Monument. The footprint of the Lincoln Memorial is a rectangle 201 ft. 10 in by 132 ft. The footprint of the Washington Monument is a square with sides of length 55 ft. 1.5 in. If both the Washington Monument and the Lincoln Memorial are on a north-south axis, how far apart are the two monuments? Conics – White House Ellipse One major section of the President’s Park, south of the White House is an area commonly known as The Ellipse. The Ellipse is a 52 acre (210,000 m2) park which is the location for a number of monuments and memorials as well as the National Christmas Tree. The real ellipse is the road that surrounds the park area. The length of the road is usually given as 5 furlongs. The National Park Service’s survey of the Ellipse gives: major axis 1058:26 feet minor axis 902:85 feet area 751071:67 square feet perimeter 3086:87 feet All measurements were taken from face to face of the curb line.
